Distributed Censorship or Extortion? The IoT vs Brian Krebs
Now it’s official. The particular website that was hit by a record-breaking distributed denial of service (DDOS) attack that we covered a few days ago was that of white-hat security journalist [Brian Krebs]: Krebs on Security.
During the DDOS attack, his site got 600 Gigabits per second of traffic. It didn’t involve amplification or reflection attacks, but rather a distributed network of zombie domestic appliances: routers, IP webcams, and digital video recorders (DVRs). All they did was create HTTP requests for his site, but there were well in excess of 100,000 of these bots.
In the end, [Krebs’] ISP, Akamai, …read more
Homebrew Powerwall Sitting at 20kWh
Every now and then a hacker gets started on a project and forgets to stop. That’s the impression we get from [HBPowerwall]’s channel anyway. He’s working on adding a huge number of 18650 Lithium cells to his home’s power grid and posting about his adventures along the way. This week he gave us a look at the balancing process he uses to get all of these cells to work well together. Last month he gave a great overview of the installed system.
His channel starts off innocently enough. It’s all riding small motor bikes around and having a regular good …read more
New SuperCon Badge is 40% Lighter and a Work of Art
The 2016 Hackaday SuperConference is just around the corner and today we get a good look at the hardware badge. It was designed by [Voja Antonic] — a legend of hardware creation who will be at the conference. I like to think of him as the Woz of the Eastern Bloc, having designed the Galaksija computer. This badge is a beautiful example of embedded design. We’ll dive into all of the details after the break.
Get your ticket now for 48-hours of talks, workshops, the Hackaday Prize party, badge hacking, and so much more.
Songbird, A Mostly 3D Printed Pistol That Appears To Actually Work
[Guy in a garage] has made a 3D printed gun that not only appears to fire in the direction pointed, it can also do it multiple times. Which, by the standard of 3D printed guns, is an astounding feat. He started with .22 rifle cartridges but has since upgraded and tested the gun with .357 rounds. The link above is a playlist which starts of with an in-depth explanation of the .22 version and moves through design iterations
This gun prints on a standard FDM printer. Other 3D printable guns such as the infamous Liberator or the 3D printed metal …read more
Line Follower with No Arduino
There’s hardly a day that passes without an Arduino project that spurs the usual salvo of comments. Half the commenters will complain that the project didn’t need an Arduino. The other half will insist that the project would be better served with a much larger computer ranging from an ARM CPU to a Cray.
[Will Moore] has been interested in BEAM robotics — robots with analog hardware instead of microcontollers. His latest project is a sophisticated line follower. You’ve probably seen “bang-bang” line followers that just use a photocell to turn the robot one way or the other. [Will’s] uses …read more
